  • Hey Gang,

    Can someone help solve this issue that has left me and my LBS stumped.

    My brother is just getting back in cycling and has just bought a new Cannondale Caad with Sora groupset.

    There seems to be an issue when shifting into the big chainring where the chain doesn't always land on the chainring and the chain hovers on the teeth before catching then has a tendency to intermittently jam between the chainring and the front mech and get "proper" stuck.

    I've attached an image of it getting stuck below with the original chain.

    Bikes been looked at by the shop he purchased from and my LBS and have not managed to solve the issue. I've now replaced the chain and chainrings to see if that would help and still seems to happen.

    Here's what I've also checked
    -BB axle doesn't seem to have play in it
    -Chain is not stiff on any links

    Any advice on anything else to try would be much appreciated trying to encourage him to get out on the bike and constant mechanicals aren't helping, or am I expecting too much from a fairly basic setup.

  • Did you orientate the two rings properly? Sometimes there are markings on the rings, or little notches.

    Looking at the screenshot from your video below, you can see a notch on the small chainring. Look for the one on the big chainring, and align these with each other.
